Definitions

  • the present invention relates to a hand-held distance measuring device, consisting of a handheld electronic device, in particular a smartphone or tablet computer, and a distance measuring module.
  • the invention also relates to a distance measuring module for use in such a distance measuring device.
  • movable or hand-held distance measuring devices For these tasks stationary, movable or hand-held distance measuring devices are used, which perform an optical distance measurement to a selected measuring point. In most cases, a laser beam is emitted and received and evaluated again after reflection at the target. To determine the distance, different measurement principles are available, such as e.g. Phase or transit time measurement.
  • portable and handheld devices are used which are applied with respect to a structure to be measured and then perform distance measurement to a surface.
  • a suitable for such applications and typical hand-held rangefinder is, for example, in the EP 0 738 899 and the EP 0 701 702 described.
  • a disadvantage of all these solutions is a high constructive and material costs, since in addition to the actual laser measurement module other components are installed to enable the operation and to increase the ease of use, resulting in a significantly increased overall cost of the meter.
  • additional components include, for example, a display, e.g. As a screen or touch screen, input means, cameras, processing units and additional sensors, such as gyroscopes and tilt sensors.
  • connection of a laser measuring module with such a hand-held device can significantly reduce the design effort and material costs compared to a solution as a stand-alone distance measuring device.
  • Hand-held laser-based distance measuring devices with a possibility to transfer data via a Bluetooth connection to other electronic Devices are already known (for example, with the "Disto TM D3a BT" or the “Disto TM D8" Leica Geosystems). However, these can also be used individually and therefore always have a user interface, that is to say a display device and input means. By simultaneously handling several devices while surveying the advantage of the hand-held solution is also largely lost. Particularly impractical is when the data exchange via a cable connection.
  • Another object of the invention is to provide such a distance measuring module which can be easily held in common with an electronic device in one hand and thereby controlled via a user interface of the electronic device.
  • a particular object of the invention is to provide such a distance measuring module, which is designed without such components, which are provided by the electronic device, in particular without a display device, input means and inclination sensors.
  • a further object of the invention is to provide such a distance measuring module which at least temporarily with a handheld electronic device to a functional handheld laser rangefinder is assembled.
  • a specific object of the invention is to provide such a distance measuring device, which allows a determination of distances between distant points.
  • the distance measuring unit according to the invention is designed for use with a handheld electronic device which has an inclination sensor for detecting at least one longitudinal inclination of the device.
  • a two-axis inclination sensor on the horizontal axis, a compass and / or a gyroscope may additionally be included.
  • the distance measuring module according to the invention may also include a tilt sensor, a compass and / or a gyroscope, for example if it is designed for connection to a specific type of electronic device that does not have these particular components or if its accuracy is insufficient for the desired applications ,
  • the distance measuring module may have such a target search camera with zoom functionality.
  • a camera of an optional image acquisition unit can additionally assume a function as a target search camera.
  • the target search camera is a camera of the electronic device connected to the distance measuring module.
  • the distance measuring module can have image deflection means which are designed to redirect the camera image of a camera of the electronic device coaxially to the laser direction, for example to use this as a target search camera.
  • the image deflection means have optical elements, in particular a mirror, lenses and / or light-conducting fibers.
  • the image deflection means are preferably arranged on a location of the distance measuring module defined by the known position of a camera of a specific type of electronic device. They may also be arranged to be movable, for example to be usable with different types of electronic devices, or to change from a position integrated in the housing of the distance measuring module to a position in front of the camera.
  • the method according to the invention also includes applying the distance measuring device to a reference object.
  • the application is carried out by means provided on the housing of the distance measuring module stop means, which - are designed, for example, with a trapezoidal cross section - so that they define a reference plane,
  • the stop means are arranged at the laser distance measuring unit opposite end of the distance measuring module.
  • the stop means are arranged in a known spatial relationship stored in a memory unit of the distance measuring module to the laser distance measuring unit, in particular the receiving unit for receiving the reflected beams, so that the reference plane also has a known spatial relationship, in particular a known distance, to the laser distance measuring unit. Adding this distance to the distance measurement result determined by the time interval will determine the distance between the reference object and the target point. This is displayed to the user on the display device.
  • the invention also relates to a computer program product with program code, which is stored on a machine-readable carrier of an electronic device, for carrying out a method for measuring a distance by means of a distance measuring module according to the invention and displaying the measured distance on a display of the electronic device, in particular if the program a trained as a computing unit of the electronic device electronic data processing unit is executed.
  • the computer program is stored on a memory unit of the distance measuring module.
  • the computer program can be copied automatically or by user request into a memory of the electronic device, or the memory unit is designed so that access to the computer program by a computing unit of the electronic device is allowed.
  • the computer program product is also for carrying out a method for calculating an angle between two emission directions suitable.
  • a span can be determined from two measured distances and a calculated angle.
  • a display device 114 On the top of the device are a display device 114 in the form of a display and input means 115 in the form of a keypad.
  • a target search camera (not shown here) with a zoom functionality for recording images that can be displayed on the display device 114 can be provided in the direction of the emission direction.
  • data can be exchanged between the two components of the distance measuring device 1, that a user by means of the input means 250 of the electronic device 200 a Measurement of the laser distance measuring unit 110 of the distance measuring module 100 can trigger and it the measurement data on the display device 240 of the electronic device 200 are displayed.
